DM74ALS09M Equivalent & Substitute Parts

Part Overview

The DM74ALS09M is a 4-channel AND gate logic IC with open collector outputs in a 14-SOIC surface mount package, manufactured by onsemi. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates within the 4.5V to 5.5V supply voltage range and is suitable for applications requiring AND logic gating with open collector output capability.

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS09M are qualified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Must Match):

• Logic Type: AND Gate
• Number of Circuits: 4
• Number of Inputs: 2
• Features: Open Collector
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output Low: 8mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay: 54ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Series: 74ALS

All substitute parts listed below meet these requirements and are therefore functionally and mechanically interchangeable with the DM74ALS09M.

Parameter Comparison

Engineering Selection Recommendations

SN74ALS09DR (Texas Instruments) is the primary substitute for new designs and production. This part carries Active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and available in Cut Tape and Digi-Reel packaging formats, supporting both automated assembly and manual component handling workflows.

SN74ALS09D (Texas Instruments) is a secondary substitute option with Last Time Buy status. This part is ROHS3 compliant and available in Tube packaging. While electrically and mechanically equivalent, its Last Time Buy designation indicates limited future availability and is suitable only for applications with defined production end dates or legacy system maintenance.

Both substitute parts are manufactured by Texas Instruments and provide identical electrical performance and mechanical compatibility with the obsolete DM74ALS09M.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS09DR and SN74ALS09D be used interchangeably with DM74ALS09M?

A: Yes. Both parts meet all electrical and mechanical parameter requirements for direct substitution. The difference lies in product status and packaging format, not functional performance.

Q: What is the difference between SN74ALS09DR and SN74ALS09D?

A: Both parts are electrically identical. SN74ALS09DR is Active status with Cut Tape and Digi-Reel packaging options. SN74ALS09D is Last Time Buy status with Tube packaging. Select based on production timeline and packaging requirements.

Q: Why is the DM74ALS09M obsolete?

A: The DM74ALS09M is classified as obsolete by onsemi. Texas Instruments manufactures equivalent 74ALS09 variants that remain in active production.

Q: Are there any compliance differences between the substitute parts?

A: Both Texas Instruments substitutes are ROHS3 compliant. All three parts share identical REACH Status (REACH Unaffected), ECCN (EAR99), and HTSUS (8542.39.0001) classifications.

Q: What packaging formats are available for substitutes?

A: SN74ALS09DR is available in Cut Tape (CT) and Digi-Reel packaging. SN74ALS09D is available in Tube packaging. Both use the same 14-SOIC surface mount package.

Q: Is there a difference in supply availability?

A: SN74ALS09DR (Active status) provides ongoing supply assurance. SN74ALS09D (Last Time Buy status) has limited future availability. For new designs, SN74ALS09DR is recommended.
